Rare Case Studies of Bilateral and Symmetric Sacroiliac Disease by Stephen Soloway, Alyxandra M. Soloway, Tyler G. Chin, Timothy Lieske

“…We present three rare conditions presenting with bilateral and symmetric SIJ disease, none of which is ankylosing spondylitis, Crohn’s colitis, ulcerative colitis, psoriatic arthritis, and reactive arthritis (Reiter syndrome); there are reports of concurrent SIJ disease in rheumatoid arthritis and SLE. …”

Point-Symmetric Multivariate Density Function and Its Decomposition by Kiyotaka Iki, Sadao Tomizawa

“…For a T-variate density function, the present paper defines the point-symmetry, quasi-point-symmetry of order k (<T), and the marginal point-symmetry of order k and gives the theorem that the density function is T-variate point-symmetric if and only if it is quasi-point-symmetric and marginal point-symmetric of order k. …”

Herrera complexity and shadows of spherically symmetric compact objects by Subhasis Nalui, Subhra Bhattacharya

“…In this work we investigate the effect of complexity factor on the formation of photon spheres for spherically symmetric compact objects. The complexity factor obtained from the orthogonal splitting of the Riemann curvature tensor connects the geometric attributes of a compact spherically symmetric gravitating object with its matter inhomogeneity and pressure anisotropy via a scalar term. …”
